Correct Answer: 48 ÷ 5 + 8 × 10 – 2 = 13
Solution : Given: – means ÷, + means ×, ÷ means –, × means +.
Let's check the options – First option: 43 × 7 ÷ 5 + 4 – 8 = 25 = 43 + 7 – 5 × 4 ÷ 8 = 43 + 7 – 5 × 0.5 = 43 + 7 – 2.5 = 47.5 ≠ 25 Second option: 48 ÷ 5 + 8 × 10 – 2 = 13 = 48 – 5 × 8 + 10 ÷ 2 = 48 – 5 × 8 + 5 = 48 – 40 + 5 = 13 = R.H.S. Third option: 36 × 4 – 12 + 5 ÷ 3 = 420 = 36 + 4 ÷ 12 × 5 – 3 = 36 + 0.33 × 5 – 3 = 36 + 1.65 – 3 = 34.65 ≠ 420 Fourth option: 42 + 5 ÷ 6 × 8 – 3 = 28 = 42 × 5 – 6 + 8 ÷ 3 = 42 × 5 – 6 + 2.67 = 210 – 6 + 2.67 = 206.67 ≠ 28
So, only the second option satisfies the given condition. Hence, the second option is correct.
